The present invention, relating as indicated to metallic wall structure, more partieularly concerns an improvedconstruction for the side walls and ceiling of spray booths. Spray booths are customarily constructed to provide an enclosure open at only one side thereof and to have a suction apparatus operating through the wall furthest from the open side to draw all of the fumes incidental to the spraying operation away from the operator and away from such opening. It is very essential that this suction be employed, both from the health standpoint and for the elimination of fire hazards. Heretofore the walls of these booths have been fabricated from flat metallic sheets having angle irons secured to theiradjacent edges and having means for securing together the contiguous faces of the angle irons. Such construct on is not only very heavy and expensive, but

has been found toineflectually seal the joint between the wall sections.

My invention provides a much simpler and more satisfactorywall construction which meets the requirement of an air-tight wall joint, and at the same time is lighter in weight and cheaper to manufacture.

To the accomplishment of the foregoing and related ends, said invention, then, 'consists of the means hereinafter fully describedand particularly pointed out in the claims; the annexed drawings and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used. In said annexed drawings Fig. ..1 is a side elevational view of a spray booth constructed in accordance with. my

' invention;

Fig. 2 a vertical sectional view on an enlarged scale taken on line 22 of Fig. 1 through the joint between the side wall and ceiling of the booth;

Fig. 3 a similar view taken on line 3-3 of Fig. 1 through the base line of the side wall; an

Figs. 4 to 9, inclusive, are horizontal sectional views as taken on line ww of Fig. 1,

lel to flanges 17 .7

and an open end 13, the flooring therefor being indicated at 14; As mentioned hereinbefore, ,in the use of this vtype of spraying booth, there is provided a suction apparatus (not shown), which acts through the wall 12 to prevent circulation of air outwardly of the open side 13. In the following description there will be described in detail the construction of one of the structural units which go to make up the entire booth, it being obv-ious thata-booth of any size may be formed by merely increasing or diminishing the number of'such units. j

In each of the modifications shown in Figs. 4 to 9, inclusive, is incorporated the main feature of the, invention in having the and an air-tight joint. Another object heresides 10, a ceiling or roof 11, a closed end 12 of is to construct these "attaching fianges so that two or more complementary surfaces of each plate 15 are provided forabutment in the assembly of units. This not only strengthens the joint whenthe plates 15,.per- V mitting the use of lighter material, but also provides a more'effective air excluding structure. I

In Fig. 4 the plates or sections 15 are as- I sembled with their respective extremities 16 in juxtaposition. At the extremities 16 the plates 15 are'angularly-bent to provide a right-angle flange 17 andalso rebent flanges 18 and 19,.the portions 18 being parallel to the plates 15 and the portions 19 being paralunits each of the several flanges 17, 18 and 19 of the adjacent plates are positioned in j close contact and a bolt 20, or like securing means, is employed to secure thev sections together. On account of the close contact In the assembly of these between the ends of the sections 15 in the I several planes incidental to the formation of flanges 17 18 and 19 the joint formed therejoint.

by is practically air-tight. This construction is found to also provide a very rigid The form illustrated in Fig. is very similar to that'of Fig. 4 having plates provided with angular flanges 17 and 18 at their extremities, which are adapted to contact with each other. In place of the flanges 19 is provided flanges 20 which do not contact at their adjacent faces, but provide a longitudinal pocket or recess 21 therebetween, in"

which is inserted suitable packing material 22 to aid in the exclusion of lightand air from the section joint. In this form the plates 17 are indicated as being secured together by spot welding, which of course renders the structure permanent.

A like construction is illustrated in Fig. 6

wherein the flanges 20 provide the recess 21,.

but in place of thepacking 22 there is inserted in this recess a suitable wedge 23. This latter member may be formed of comparatively light spring metal in the shape of a V, which maybe driven, into the recess 21 to seal the same. Similarly, Fig. 9 shows a joint'between the plates 15 having suitably spaced parallel flanges 20 and another form of sealing device. This device consists of a U-shaped metallic member 24 which is attached to the flanges 20 with its open ends engaging the outer surfaces of such flanges.

:This U-shaped member is constructed of spring material and serves to not only seal the outer ends of the plates 15, but also to keep the flanges 17 pressed into close contact with each other. a

Fig. 8 illustrates a joint having the ends of plates 15 bent into flanges 17, 18, 19 and 20, together with a detachable metallic strip 25 which, when assembled to the joint between plates 15, is adapted to engage the outer surfaces of each of said several flanges. Abolt' 26 is provided to secure the ends 27 of member 25 to the flanges 17 1 Fig. 7 illustrates a joint having the plates 15 bent at their extremities into right-angle flanges 28 similar to flanges17 and with oppositely bent portions 29 and 30. Secured to the flanges 29 and 30 is a supplemental plate 31 adapted to have close contact with the outer surfaces of such flanges to prevent air from passing therebetwe'en. This member 31 in this form ofjoint serves also as a means for attaching the sectionslfi together.

.The several sections in the construction of a spray booth may besecured to the floor 14:

by a right-angle plate 32 having one surface thereof secured by bolts 33 to the floor and having the other surface 34 extendingvertically, to which may be attached the lower vertical end of the p1ates'15. At the upper end of such plates or sections is provided an angular striphaving a vertical flange 35 extending closely parallel to the inner surface of the plates 15and'having a horizontal or 38, which serves to strengthen the entire structure, aswell as to hide from view the joints in the sealing structure.

Other modes of applying the principle of myinvention may be employed instead of the one explained, change being made as re gards the mechanism herein disclosed, provided the means stated by any of the followingclaims or the equivalent of suchlstated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. A self-supported metallic wall comprising a plurality of aligned fiat sections'having integral multi-bent angular'fla'nges atitheir adjacent edges of Z shape, the surfaces of which are at right angles, two surfaces of the Z shaped flanges on each of said adjacent edges being parallel and in contact, and resilient means engaging the outer portions of said flanges adapted to maintain the abutment of said'flanges and render the joint substantially air tight.

2. A self supported metallic wallcompris-' ing a plurality of sections having their side edges formed with a rightangular flange, the flanges of adjacent sections'being' parallel and in abutment,.other flanges formed at an angle to saidfir'st flanges, said last named flanges being also parallel and in en'- gagement with each other, and additional flanges, allof said flanges forming a Z in which the surfaces arelat'right" angles, and

said sections together.
